Q. Gabriella went shopping for a new phone. Sales tax where she lives is 9%. What number should she multiply the price of the phone by to find the total plus tax in one step?Answer:
Calculate Total Cost: To find the total cost including tax in one step, Gabriella needs to multiply the price of the phone by a factor that includes both the original price and the sales tax. The sales tax is 9%, which means that for every dollar, an additional $0.09 is charged as tax.To include this in the original price, we add 1 (representing 100% of the original price) to 0.09 (representing the 9% tax).Calculation: 1+0.09=1.09
Factor for Tax Inclusion: Gabriella should multiply the price of the phone by 1.09 to find the total cost including the 9% sales tax in one step.
